Windows 10: Sudden GPT Partition Protection

I have a desktop running Windows 10, with all updates in place. In the middle of a simple task, my computer suddenly shut down. Turning it back on, the drive is now Grayed and no longer has a drive letter assigned. The grayed out area now shows GPT Partition Protection. I Can Not 'Clean" the drive because I have data on it that I need. How can I correct the problem without erasing everything and starting over. How can I restore it to the proper configuration with completely erasing it?

clone MBR HD to bootable GPT partition?

Hi,

1. You cannot convert mbr to gpt without data loss. otherwise, you can follow directions here:

FROM WINDOWS RECOVERY CONSOLE:

To change a master boot record disk into a GUID partition table disk using a command line

• 
  Back up or move the data on the basic master boot record (MBR) disk you want to convert into a GUID partition table (GPT) disk.
  
• 
  Open an elevated command prompt (right-click Command Prompt, and then click Run as Administrator) and type diskpart. If the disk does not contain any partitions or volumes, skip to step 6.
  
• 
  At the DISKPART prompt, type list disk. Make note of the disk number you want to convert.
  
• 
  At the DISKPART prompt, type select disk <disknumber>.
  
• 
  At the DISKPART prompt, type clean.
  

2. I'd suggest converting your vista drive to a virtual machine, load that up on your windows 10 system and use a program like virtualbox to run it.

 

Convert only one partition on the disk from MBR to GPT

Follow the steps listed here on using GPTgen. He also lists how to create and restore backups.

Converting MBR to GPT without deleting your partitions

 

Delete Protected Recovery Partition (GPT Disk)

I think so. Maybe it's a separate storage from the main 32GB system drive because it's being seen as USB 2.0.

Even the Parted Magic Live USB OS can't get rid of it.









Anyway, I'll just leave it as it is. It's not affecting Windows performance anyway.
Thanks all for your help and suggestions. I will mark this thread solved but feel free post more suggestions.
